I have a basic blackburn trakstand magtrainer.
Blackburn / 2007 / Trainers
It works fine. I put the bike on it and I can ride.
It has 3 resistance levels. I notice more from the gearing of the cycle.
I think it is loud. Maybe they all are.
I know some have a remote so you can change resistance without getting off.
I don't use it very much as it bores me to tears
It was pretty cheap if I remember though.
